Where 107 fits
Why 107 is special
Only a few dozen atoms have ever been made, each surviving seconds at most. Naming it required resolving a long dispute between American, Soviet and German laboratories over who had discovered which superheavy elements — a row settled by committee in 1997.

Binary
1 1 0 1 0 1 1
1 × 64 + 1 × 32 + 0 × 16 + 1 × 8 + 0 × 4 + 1 × 2 + 1 × 1 = 107
Octal
1 5 3
1 × 64 + 5 × 8 + 3 × 1 = 107
Hexadecimal
6 b
6 × 16 + b × 1 = 107
Read as powers of two: 64 + 32 + 8 + 2 + 1 = 107.
In historical numeral systems
Egyptian
1 coil of rope, 7 strokes
1 × 100 + 7 × 1 = 107. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 vertical wedge (sixties place), 4 corner wedges + 7 vertical wedges (units place)
1 × 60 + 47 = 107. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
rho, then zeta, marked as a numeral
rho-zeta + keraia
rho + zeta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
qof, then zayin
qof-zayin
qof (100) + zayin (7) = 107, written in descending order.
Maya
1 bar (upper, twenties place) over 1 bar + 2 dots (lower, units place)
5 × 20 + 7 = 107. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Bohrium and meitnerium were named in the same 1997 IUPAC settlement that ended thirty years of competing American, Soviet and German discovery claims.

Strength 0.50, confidence "high".
Science
The superheavy elements were claimed simultaneously by American, Soviet and German laboratories, and the disputes over priority ran for decades. Bohrium's name was fixed by an IUPAC settlement in 1997 rather than conceded by the rival claimants.
